US-Israel-Iran conflict enters its fifth day (late March 3, 2026, ~11 PM PKT), Iraqi Shia militias (mostly Iran-backed groups within or linked to the Popular Mobilization Forces - PMF/Hashd al-Shaabi) have emerged as a significant secondary front. They’re acting as part of Iran’s “Axis of Resistance” to retaliate against US/Israeli strikes, but their involvement is asymmetric—mostly low-to-medium intensity drone/rocket attacks on US-linked targets in Iraq and threats to expand regionally. This draws Iraq deeper into the conflict, risking domestic instability and US preemptive responses.
Background on Iraqi Militias
The PMF is an official Iraqi state security umbrella (integrated since 2016) with ~150,000-200,000 fighters, but many factions remain loyal to Iran over Baghdad. Key Iran-aligned groups include:
- Kataib Hezbollah (US-designated terrorist group): Hardline, ideologically closest to IRGC; focuses on anti-US ops.
- Harakat Hezbollah al-Nujaba: Similar hardline stance; involved in Syria/Iraq fights.
- Asaib Ahl al-Haq (AAH): Politically influential (part of Shia Coordination Framework); more restrained due to parliamentary/government roles.
- Kataib Sayyid al-Shuhada and others: Smaller but active in claims.
- Front/coalition names: Islamic Resistance in Iraq (umbrella for claims); Saraya Awliya al-Dam (often a cover for larger groups).
These militias have historically targeted US forces (e.g., 2020-2024 attacks) to push withdrawal. US troops largely left federal Iraq in Jan 2026 but remain in Kurdistan (e.g., Erbil airport/base, Harir).
Current Role in the Conflict (as of March 3, 2026)
They joined quickly after Feb 28 strikes/Khamenei’s death:
- Attacks claimed/launched:
- Islamic Resistance in Iraq claimed 28+ attacks (March 2) with dozens of drones/missiles on “enemy bases” in Iraq/region (videos show launches; no confirmed major successes/interceptions noted).
- Saraya Awliya al-Dam: Claimed drone “swarm” on former US Victory Base/Baghdad Airport (March 1-2; one drone crashed into Iraqi Special Ops HQ; another intercepted).
- Drone strikes on US-linked sites in Erbil (Kurdistan; March 1-2), causing power outages at key gas fields.
- Ballistic missile claims by Kataib Hezbollah/Harakat al-Nujaba on US bases in Iraqi Kurdistan/Kuwait (March 2; unverified impacts).
- Threats to expand: Kataib Hezbollah condemned UAE/Saudi for supporting “Zionist-American project” and claimed US jets/drones operate from Jordan—threatening attacks there. Some unverified claims of strikes on Saudi Aramco.
- US/Israeli countermeasures: Preemptive airstrikes (Feb 28-March 2) hit PMF/Kataib Hezbollah sites in Jurf al-Sakhr (south Baghdad), Diyala, al-Qaim, Samawah, Ninewa Plains, Mosul checkpoint. Casualties: 4-8+ killed, several wounded (e.g., 4 in one Jurf strike; 2 in another).
Iraqi gov’t (PM Sudani) condemned attacks undermining stability, blocked Green Zone access, deployed riot police vs. militia protests. Some militias (e.g., AAH-linked) show restraint to protect political gains.
Military Capacities and Sustainability
These groups excel in asymmetric warfare but face limits:
| Aspect | Key Strengths | Limitations & Risks | Sustainability in Current War |
|---|---|---|---|
| Manpower | Tens of thousands (PMF total ~150k+); recruitment surges (e.g., Diyala pledges). | Ideological splits; some prioritize Iraq politics over Iran loyalty. | Medium—can sustain low-level ops months; high attrition if US escalates strikes. |
| Weapons | Iranian-supplied drones (Shahed-like), short/medium-range missiles, rockets; years of stockpiling. | Degraded by preemptive strikes; limited precision/success against defended US sites. | Medium—drones cheap/effective for harassment; missiles risk rapid depletion. |
| Strategy | Hit-and-run on US/Kurdish targets; claim via coalitions to avoid direct blame. | Exposed to airstrikes; Iraqi gov’t pressure to disarm/restrain. | High short-term (weeks); could prolong via attrition but risks isolating Iraq. |
| Coordination | IRGC support; pre-war planning meetings reported. | Not fully unified—some (AAH) more cautious. | Variable—strong vs. US; weaker if Iran collapses further. |
Overall: Not game-changers for Iran (unlike Hezbollah’s past scale), but effective for imposing costs on US presence, diverting resources, and showing solidarity. Low success rate so far (many intercepted/failed), but persistent harassment could strain US defenses.
Broader Implications
- Iraq as parallel theater: Widens war without direct Iran involvement; risks sectarian tensions, protests, or gov’t collapse if militias push too hard.
- US posture: Preemptive strikes degrade capabilities; Trump vows more if needed. Remaining US forces in Kurdistan vulnerable.
- Regional spillover: Threats to Jordan/Kuwait/Saudi could pull Gulf deeper; echoes 2024 Jordan outpost attack (3 US killed).
- For Pakistan/Lahore: Indirect—higher oil volatility from regional instability; potential remittance/trade hits if Iraq destabilizes. No direct links, but monitor energy prices and cyber threats.
Iraqi militias’ role is classic proxy: Retaliate asymmetrically to bleed US will, avenge Khamenei, and deter full regime change in Iran—while Baghdad tries to contain fallout. If Iran weakens more, expect intensified militia ops or restraint if Baghdad pressures hard. Watch for: More claims tonight/tomorrow, US responses in Kurdistan, or Jordan threats materializing.
